 * The house design system (RiLiGar Zen) as plain CSS, for the two HireSys prototypes (site and system).
 * Values copied from packages/components-kit/src/theme.js and packages/dashboard-kit/src/tokens.css:
 * one face (Montserrat 500/700/800/900), one ramp of greys, radius 0, no shadow, 1px gray.2 hairline.
 * Dark mode is the kit's ramp by elevation (12-modo-escuro.md): the names keep their role, the values move.
